Long-term Outcomes After Initial Presentation of Diverticulitis.

Area of Science:

• Gastroenterology
• Surgical Gastroenterology
• Health Services Research

Background:

• Long-term outcomes of diverticulitis are not well-defined.
• Current practice guidelines for diverticulitis lack robust evidence.
• Understanding recurrence and mortality is crucial for patient management.

Purpose of the Study:

• To determine long-term outcomes of diverticulitis.
• To inform current practice patterns for diverticulitis management.
• To analyze recurrence, treatment, and mortality after emergent diverticulitis admission.

Main Methods:

• Utilized the California Office of Statewide Health Planning and Development database (1995-2009).
• Analyzed longitudinal data for patients with emergent diverticulitis admission.
• Assessed recurrence rates, medical vs. surgical treatment, and mortality post-recurrence.

Main Results:

• 85% of patients managed medically after emergent diverticulitis did not recur.
• Recurrence occurred in 16.3% of medically managed patients.
• Predictors of mortality with recurrence included age >50, tobacco use, and complicated initial presentation (obstruction, abscess, peritonitis, sepsis, fistula). Mortality for delayed elective surgery was 0.3% vs. 4.6% for emergent resection during a second episode.

Conclusions:

• Initial medical management is successful for the majority of emergent diverticulitis cases.
• Diverticulitis recurrence is associated with significantly worse outcomes.
• Surgical resection should be strongly considered for patients over 50 or those with complicated initial diverticulitis presentations.
